Description

Piston M-7416-100 (1.00 mm) The M-7416-100 1.00 mm Oversize Steel Crown Piston Set (x4) is a premium OEM-grade piston set engineered for diesel engines that require a 1.00 mm oversize piston due to severe cylinder wear, scoring, or full machining/reboring. Designed with a steel crown , this piston set delivers unmatched durability, exceptional heat resistance, and superior strength—making it ideal for high-performance, turbocharged, and heavy-duty diesel applications. Steel crown pistons outperform traditional aluminum pistons under extreme temperature and high-boost environments by preventing crown erosion, cracking, and premature wear. Each piston in this set is precision-machined to restore proper piston-to-liner clearance, achieve optimal compression, and ensure efficient sealing for smooth, reliable engine operation. This set includes 4 pistons , replacing OEM reference 3926634 , offering perfect OEM-spec compatibility for engines requiring extensive machining correction or performance-grade rebuilds. ✔ Key Features & Technical Advantages OEM-spec M-7416-100 1.00 mm oversize steel crown piston set (x4) Designed for cylinders rebored or machined 1.00 mm oversize Steel crown construction ensures unmatched heat, boost & load resistance Restores compression, improves fuel efficiency & stabilizes combustion Precision-machined ring grooves & skirts for reduced friction and smoother operation Minimizes blow-by, oil burning, smoke & piston slap Ideal for severe-duty, turbocharged, industrial & high-output diesel engines Direct replacement for OEM 3926634
